The copper casting rotor, including：One copper casting rotor core main body, an armature spindle, an air intake cast copper fan blade device and
One air draft cast copper fan blade device, the copper casting rotor core main body is provided with a central through hole, equal positioned at the central through hole surrounding
It is even that multiple wind guide tanks are distributed with；The air intake cast copper fan blade device and an air draft cast copper fan blade device are fixed respectively to be connected
It is connected to the rear and front end of the copper casting rotor core main body；The armature spindle be sequentially inserted into the air intake cast copper fan blade device,
Copper casting rotor core main body and air draft cast copper fan blade device, during assembling in the armature spindle and the copper casting rotor core main body
Heart through hole is in interference fit.
The air intake cast copper fan blade device and an air draft cast copper fan blade device by welding respectively with the casting
Copper rotor core main body is fixed.
Due to the mining explosion-proof type motor of said structure, one side explosion-proof motor shell is provided with cooling water circulation chamber, prevents
Quick-fried motor internal rotor uses copper casting rotor, and the front end of copper casting rotor core main body be provided with air intake cast copper fan blade device,
Centre is provided with multiple wind guide tanks and rear end is provided with air draft cast copper fan blade device, and the heat that high speed rotor is produced is extracted out by fan
Cooled down by cooling water circulation chamber again afterwards, so, the self-radiating of mining explosion-proof type motor is preferably solved the problems, such as, so as to improve
The reliability of whole motor.
